The **TV1020-3R0605-R** is a high-performance **Supercapacitor** (also known as an Electric Double-Layer Capacitor or EDLC) manufactured by Eaton (formerly Bussmann). It belongs to the TV series, which is designed for high power and high energy density applications. --- ## 1. Technical Specifications Below are the primary electrical and physical characteristics of the component: | Feature | Specification | | :--- | :--- | | **Capacitance** | 6.0 Farads | | **Voltage - Rated** | 3.0 Volts | | **Tolerance** | -10%, +30% | | **ESR (Equivalent Series Resistance)** | ~40 mΩ (Typical) | | **Operating Temperature** | -40°C to +65°C (Extended to +85°C with derating) | | **Termination Style** | Through-hole (Radial Leads) | | **Dimensions** | 10mm (Diameter) x 20mm (Length) | | **Life Cycle** | Up to 500,000 cycles | --- ## 2. Key Features and Design ### High Voltage Rating Unlike standard supercapacitors that often peak at 2.7V, the TV series is rated for **3.0V**. This allows for higher energy storage ($E = \frac{1}{2}CV^2$) and provides a greater safety margin in 2.8V or 3.0V systems. ### Low ESR The low internal resistance allows the device to discharge high currents quickly without significant voltage drops or heat generation. This makes it ideal for "pulse" power applications. ### Environmental Compliance * **RoHS Compliant:** Free of lead and other hazardous substances. * **Halogen-Free:** Safe for modern environmental standards. --- ## 3. Common Applications This specific part is typically used in circuits requiring bridge power or peak current assistance: 1. **Smart Meters:** Provides power for RF transmissions (GSM/GPRS) during data bursts. 2. **Industrial Backups:** Acts as a "UPS" for small controllers or PLCs to allow for graceful shutdowns during power loss. 3. **IoT Devices:** Used in solar-powered sensors to store energy during the day for use at night. 4. **Automotive:** Powering GPS trackers or emergency e-call systems. --- ## 4.
